WGU Secure-Software-Design Dumps - Pass WGU Secure Software Design (D487, KEO1) Exam in First Attempt 2026

The WGU Secure-Software-Design - WGU Secure Software Design (D487, KEO1) Exam is part of the WGU Courses and Certifications track and is designed for learners who want to build strong knowledge of secure software architecture and design. It is a valuable exam for candidates who need to understand how to create reliable, scalable, and secure software systems. Passing this exam shows that you can apply core design principles in practical software environments and support better system quality and security.

# Exam Topics Sub-Topics Approximate Weightage (%)
1 Software Architecture and Design Architecture principles, design goals, system structure 20%
2 Software Architecture Types Layered, client-server, microservices, modular design 15%
3 Design Pattern Selection and Implementation Pattern purpose, pattern selection, implementation use cases 18%
4 Large Scale Software System Design Scalability, distributed design, performance planning 17%
5 Software System Management Maintenance, monitoring, change control, lifecycle support 15%
6 Reliable and Secure Software Systems Security controls, fault tolerance, reliability, risk reduction 15%

This exam tests more than memorization. It checks how well candidates understand software design choices, architecture tradeoffs, secure implementation concepts, and the ability to apply those ideas in real-world system planning. You should expect questions that measure practical judgment, design awareness, and depth across both reliability and security topics.

Actual WGU Secure-Software-Design Exam Questions

Question 1

The software security group is conducting a maturity assessment using the Building Security in Maturity Model (BSIMM). They are currently focused on reviewing attack models created during recently completed initiatives.

Which BSIMM domain is being assessed?

Correct answer: C

The Intelligence domain in the Building Security in Maturity Model (BSIMM) focuses on gathering and using information about software security. This includes understanding the types of attacks that are possible against the software being developed, which is why reviewing attack models falls under this domain. The BSIMM domain of Intelligence involves creating models of potential attacks on software (attack models), analyzing actual attacks that have occurred (attack intelligence), and sharing this information to improve security measures. By reviewing attack models, the software security group is essentially assessing the organization's ability to anticipate and understand potential security threats, which is a key aspect of the Intelligence domain.


Question 2

Which secure coding practice involves clearing all local storage as soon as a user logs of for the night and will automatically log a user out after an hour of inactivity?

Correct answer: D

The practice of clearing all local storage when a user logs off and automatically logging a user out after an hour of inactivity falls under the category of Session Management. This is a security measure designed to prevent unauthorized access to a user's session and to protect sensitive data that might be stored in the local storage. By clearing the local storage, any tokens, session identifiers, or other sensitive information are removed, reducing the risk of session hijacking or other attacks. The automatic logout feature ensures that inactive sessions do not remain open indefinitely, which could otherwise be exploited by attackers.


Question 3

Which type of security analysis is performed by injecting malformed data into open interfaces of an executable or running application and is most commonly executed during the testing or deployment phases of the SDLC?

Correct answer: B

Question 4

Which mitigation technique is used to fight against an identity spoofing threat?

Correct answer: A

To combat identity spoofing threats, a mitigation technique that is often used is requiring user authorization. This involves implementing strong authentication methods to verify the identity of users before granting access to sensitive information or systems. Techniques such as two-factor authentication (2FA) or multi-factor authentication (MFA) are effective in reducing the risk of unauthorized access, as they require users to provide multiple pieces of evidence to confirm their identity, making it much harder for attackers to spoof an identity successfully.


Best practices for preventing spoofing attacks, including the use of antivirus and firewall tools, and the importance of strong authentication methods like 2FA and MFA1.

The National Security Agency's guidance on identity theft threats and mitigations, emphasizing the need for personal protection and strong authentication measures2.

Discussion on the effectiveness of strong authentication methods in protecting against spoofing attacks3.

The role of comprehensive identity verification and authentication strategies in preventing AI-enhanced identity fraud4.

Question 5

The product security incident response team (PSIRT) has decided to make a formal public disclosure, including base and temporal common vulnerability scoring system (CVSS) scores and a common vulnerabilities and exposures (CVE) ID report, of an externally discovered vulnerability.

What is the most likely reason for making a public disclosure?

Correct answer: C
